Since most people are familiar with Berzerk, I'll only use this review to touch on the musical differences. Basically, the new soundtrack is so good and lasts for so long that it makes the game a lot more enjoyable. I've been known to stick this cart in and just let the music play while I'm doing other tasks. While this might be kind of common for newer games, this is the only 2600 cartridge that I've ever even thought about doing it with.
The game is excellent. It might not be different enough to warrant a
purchase, but I don't regret it at all. If you are a fan of Styx, the
song Mr. Roboto or Berzerk in general, you need to at
least check this interesting title out!
